The terrorist attacks of September 11, 2001, made Americans aware of their vulnerability and concerned about their safety. The government responded in part by establishing the Department of Homeland Security, instituting new rules for travel, and passing the Patriot Act. Many people think that some of these changes curtail our civil liberties unduly. Others think that giving up some liberty for safety is a worthwhile trade. In A PRO/CON LOOK AT HOMELAND SECURITY: SAFETY VS. LIBERTY AFTER 9/11, author Kathiann M. Kowalski examines the arguments on both sides of the debate. In addition, she outlines the changes that have taken place and looks at the future of homeland security.
